I have acquired a 95 Nissan Altima XE.

So, I got two engine codes. P0325 Engine Knock Sensor and P1400, which I have yet to figure out what that is yet. There is no knocking noise coming from the engine, but when it is idling for a few minutes or so the rpms will drop. Should I worry, or are these simple fixes?

As for knock, do a tune up, change fuel filter, better gas, etc.. May even be bad Knock sensor
